Do It Yourself

Hi all,

Recently got myself a popcorn maker from the thrift shop that unfortunately refused to work. Wanted to try and get it operating as it should again, but it seems the issue wasn't so much something being broken in the machine, but rather extremely cheap build quality.

Repairing the thing just didn't seem worth it, so I disassembled it and am recycling the individual parts. However, I am thinking about making a toolbox so that I can learn some repairs and all, and am hoping to save the screws that I've salvaged from the machine.

My question is this. How does one sort and categorize the screws they keep? Are there codes the screws have, or does it come down to personally measuring and determining the length and type of screwdriver needed for them? Currently just keeping them in a sandwich bag for the time being.

Thanks for any help in advance.
